Recently I have started digging more into the Microkorg, and I must say that I like it better now than earlier. I think I just never gave it a better chance. It's not as dirty and screamy as the Nord, but I'd say it beats the 201 when it comes to dirty leads. It's also pretty nice for EFX sounds, which it will now probably be dedicated to in most cases. As long as I keep it away from pads etc, the polyphony won't annoy me. At times I think the saw gets boring though... it simply sounds too much the same all the time, so Im getting tired of it after some time.
It definitely also helps on the creativity when you get more into the matrix system, and simply get a better feeling of where the specific feature is in the matrix.
A bad thing is that after some time those knobs have been tweaked too much, as if they have gone a little loose compared to a few minutes earlier.
